Specification of Letters Patent. Application filed March 8, 121.19.Serial No. 482,006.

- Patented May 24', 1910.

To all whom it may concern:

Be it known that I, LOUIS LAPERSONNERIE, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedConcrete l/Vall Construction, of which the following is a full, clear,and exact description.

The object of the invention is to provide a new and im iroved concretewall constructo provide suitable furring strips for fastening doorframes, base boards,

picturemoldings and the like securely in place on the wall, the saidfurring strips forming integral parts of the blocks of concrete or otherplastic material.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this Specification, in

which similar characters of reference indicate corresponding parts inall the views.

Figure 1 is a perspective view of the improvement; Fig. 2 is a similarview of a modified form of the same; Fig. 3 is a front end view of oneof the base blocks; Fig. 4

is a side elevation of the same; Fig. 5 is av rear end view of the same;Fig. 6 is a sectional lan view'of the same on the line 6-(3 of Fig. 4:;Fig. 7 is an end view of the base block wall construction shown in- Fig.

. 2; Fig. 8 is a side elevation of the same;

. is a sectional Fig. 9 is a plan view of the end fur-ring strip and itsanchor; Fig. 10 is a plan view of one of the blocks having air spaces;Fi 11 Ian view of a modified Form of the base b ock; and Fig. 12 is across section of one of the furring strips for the block shown in Fig.11. I

The wall shown in Fig. 1 is formed of base blocks A, intermediatecourses of concrete blocks B and a course of top blocks C, and each baseblock A has embedded in it opposite longitudinal furring strips D,preferably made of wood and of dovetail shape, so as to form an integralpart of the block without danger of pulling out of the same. Thelongitudinal furring strips D of each block A are connected with eachother by cross bars D, preferably notched, as indicated in Fig. 6, toassist in holding the longitudinal furring strips D against pulling outof the block in a lateral direction. Each base block A is also providedon each face with vertically disposed furring strips E, preferably ofdovetail shape and extenda distance of the longitudinal furring stripsD; By the arrangement described the base board can be readily secured inplace onthe furring strips D and E by the use of nails, screws or otherfastening devices.

In the outer ends of the blocks A and B at the door and window openingsare embedded vertically disposed furring strips F to which the doorcasings are secured by suitable fastening devices, each furring strip Fbeing preferably of dovetail shape at the sides and ends, as indicatedin Figs. 3, 4 and 6, and the outer faces of the furring strips F areflush with the ends of the blocks A and B, and. the sides, top andbottom of the furring strips F terminate distances from thecorresponding sides, top and bottom of the blocks A and B, as will bereadily understood by reference to Figs. 1 and 3. Each .furring strip Fis provided at its back with a staple F (see Figs. 4, 6 and 9) on whichis fulcrumed an anchor F embedded in the concrete material of the blockA or B. By this arrangement the furring strip F is securel held againstpullin out of the'block in a dition to the dove- Each upper block C isprovided with a ing from the bottom of the block to within furring stripG extending longitudinally and embedded in the corresponding side of thebloclrC, to allow of fastening picture moldings and the like to thefurring strip the des red distance from the ceilin The furring stri s Gare projected a distance beyond the ace of the block C, and the baseblocks A are provided with offsets A a distance above the furring stripsD so as to provide space for .the plaster H to extend from the flangeAto the furring strip G, thus rendering the face of the plaster H flushwith the sides of the base blocks A and the furring strips G. The levelI, shown in Fig. 1, shows that the faces of the furring strips D and. Glie in the same vertical plane, and a sufiicient space is providedbeportion of the wall, the furring strips are slightly projected beyondthe ends of the blocks A, so as toaccommodate the cement or otherbinding material J used between adjacent blocks, to unite the same. Asindi cated in Figs. 2, 7 and 8, the base blocks A the intermediateblocks B and the upper blocks 0 are all of the same thickness, and inthis case the longitudinal furring strips D for the base blocks Aproject beyond the sides thereof similarly to the furring strips G inthe upper blocks C, and in this case the plaster H is applied to thewall between the projecting portions of the furring strips D and G, torender the face of the plaster flush with the faces of the furringstrips D and G;

In the modified form shown in Fig. 11, the block K is provided on itssides with vertically-disposed grooves K, for receiving furring strips Lto be inserted in the grooves K.

From the foregoing it will be seen that by the arrangement described thefurring strips form integral parts of the corresponding concrete blocksand are securely embedded therein, so as to prevent the furring stripsfrom pulling out under strain.

It is understood that although I have particularly referred to concreteblocks, the invention is applicable to blocks of plaster of paris, orother plastic materials.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A concrete block provided with a longitudinal furring strip embeddedin one face thereof and having extensions projecting beyond the ends ofthe same, said extensions forming a continuous nailing strip over thejoint and producing aspacing means for the blocks, a plurality ofvertical furring stri s embedded in the block below the longitu inalstrips, and a furrin strip embedded in one end of the block, said stripbeing spaced from the sides, to and bottom of the block.

2. A concrete b ock provided with furring strips embedded in oppositesides of the block and having extensions projecting beyond the ends ofsaid block, said extensions esaeeo forming a continuous nailing stripover the joint and producing a spacing means for the blocks, andtransverse bars connecting the said strips.

3. A concrete block provided with a longitudinal strip embedded in oneface thereof and having its ends projecting beyond the ends of theblock, said projecting ends form ing a continuous nailing strip over thejoint and producing a spacing means for the blocks, and a plurality ofvertical furring strips in the said face of the block below thelongitudinal furring strip.

4. A concrete block provided with a longitudinal furring strip embeddedin a face of the block and projecting beyond the ends thereof, wherebyprovision is made for properly spacing the blocks and forming a continuous strip over the oint of the blocks.

5. A concrete block provided with a longi-' tudinal furring stripembedded in a face of the block and projecting beyond the ends thereof,the furring strip being dovetailed,

the projecting ends of the strip serving as a means for spacing theblocks and forming a continuous strip over the joint of the blocks.

6. A concrete wall, comprising blocks, the base block having its upperportion reduced in thickness, a shoulder being formed at the base of thereduced portion, and the other blocks being of the same thickness asthe.
